Equilibrium, a new Matrix-style sci-fi thriller from director Kurt Wimmer, has gone all-out on authoritarian style to create a 1984-type vision of the future. The production team shot in Berlin to get that totalitarian, stripped classical look, using the Palace of Justice, the Reichstadt, the Deutschehalle and the Brandenburg Gate for locations. Here's a good gallery of surviving Third Reich-era architecture. Other films that have passed into stylistic lore include, naturally, Metropolis and Blade Runner, as well as the Fifth Element, Brazil and even Judge Dredd. Interestingly, Equilibrium even has its own conspiracy. See also Hugh Pearman'sthings piece on Tempelhof airport.
